> Sometimes I think we're unconsciously drawn to marry others similar to us with problems, accentuating it for the next generations.Unfortunately for humans, it seems as though despite this possibly being genetic "vulnerabilities", it often (or even mostly) isn't serious enough to stop the afflicted individual from reproducing. Thus, it has been perpetuated throughout time. Even if the condition eventually incapacitates the person, often by that time the children have been born, and human altruism takes over: other members of family or society take care of them. Pure, unadulterated evolutionism without altruism would surely have eliminated these genotypes by now. Then again, altruism is a product of natural selection also.
